Chelsea manager Guus Hiddink says defender John Terry is not fit to face Stoke City this afternoon.
The Englishman continues his recovery from injury with attacking midfielder Pedro also certain to miss today's game.
Striker Diego Costa will be in the starting line-up but is expected to be replaced in the second half of the game.
"He's [John Terry is] not fit to start this weekend," Hiddink said.
"He's with the physios and he's also training but he's not with the group yet. We'll see how it goes for Wednesday.
"Pedro is the same. He hasn't practised with the group yet. He is getting treatment but also running and exercising on the pitch.
"He [Diego Costa] is in perfect physical shape, but we also must be careful not to overload him in games. We monitor them with the data of the medical team and I can make some conclusions from that.
"We are living in an emotional world but sometimes you have to be rational as well.
"I talk with him about his physical state, which is superb. There is always a danger of him doing too much, and if I share the figures with him he can be rational as well. We must let him go but sometimes I must put him on a leash.
"He wants to play every game. It's difficult to put a brake on him. Tomorrow he will start but maybe he will not play the full game.
"[The Top Four?] Others are knocking on the door, like West Ham are doing. There are more candidates for fourth position than the teams who have lost recently.
"Stoke are close as well, so it's even more necessary that from our side we have a serious approach tomorrow."
